If you've got an idea for a videogame but think you need to be a coding genius to make a game, think again. Some of the best smartphone and tablet game apps are created with simple software.

In fact, several game maker sites require no computer coding whatsoever. All you need to have is a good idea, some computer skills, and the patience to test out the game to make sure it's working.

If you're just creating it for your own enjoyment, you can have a game up and running in just a few hours. Or, spend a few weeks on it, and you can turn your idea into a potential moneymaker.

One site to do that on is GameSalad. It charges a subscription fee for its basic plan (15-day free trial, then $19 a month or $199 per year). The thing that's great about GameSalad is that it's designed to be easy to use.
